Study and Development on the Organic Cationic Flocculant Zheng Huaili, Shu Xingwu Abstract At present, the organic cationic polymer
flocculants have been received more and more concerns from scientists and technologists
extensively, the remark able progresses has been obtained. The commentary and introduction
on researching development and application of the cationic organic flocculants at home and
abroad have been introduced in this article, including the graft copolymerization of
cationic polyacrylamide, hydroxyl etherification, variety of two alkenes two alkyl
halogenated ammonium, the reaction product of epichhydin and amine, etc. Especially,the
synthetic nonpoisonous cationic polymer flocculants and the modified cationic polymer
flocculants from natural polymer such as starch in recent years are summarized and
discusseed.
有机阳离子高分子絮凝剂 郑怀礼 舒型武 摘要 近年来,有机阳离子高分子絮凝剂得到国内外学者的广泛重视。它的研究、开发、应用都取得了显著进展。本文对此进行评述和介绍，内容涉及阳离子型聚丙烯酰胺接枝共聚物、羟基醚化类、二烷基二烯丙基卤化铵类和环氧氯丙烷与胺反应物，特别是近年来淀粉等天然高分子改性阳离子型絮凝剂和人工合成的无毒有机阳离子高分子絮凝剂。 郑怀礼 男，44岁，教授，博士，主要从事为絮凝剂的制备与应用的研究。 |
